I installed El Capitan today and have noticed an odd problem with available space on the SSD. Before the install the drive had 130GB available but dropped to 82GB after the install. Weird enough but then I trashed a 50GB file and as it was emptying from the trash the available SSD space actually steadily DROPPED to 62GB. Any insights?

The OS needs swap space just to run...maybe that process is a bit rough in the beta. Otherwise, be sure to file bugs.
